About this study
Official title: Investigation of the Acute Effects of Rigid Taping on Hand Grip Strength in Individuals With Increased Elbow Valgus Angle
This study aims to investigate the acute effects of rigid taping based on the Mulligan Concept on elbow valgus angle, hand grip strength, and pinch strength in healthy young adults with an elbow valgus angle of 15 degrees or greater.
A total of 25 healthy young adults aged 18 to 25 years were randomly assigned to either an experimental group receiving rigid taping or a control group receiving placebo taping. Elbow valgus angle, hand grip strength, and three types of pinch strength (lateral, tip, and three-point pinch) were assessed at baseline (before taping) and 20 minutes after the taping application.
The main objective is to determine whether rigid taping based on the Mulligan Concept provides greater immediate improvements in elbow valgus angle, hand grip strength, and pinch strength compared with placebo taping.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Rigid TapingBehavioural
Rigid taping was performed based on the biomechanical correction principles of the Mulligan Concept, a manual therapy approach aimed at supporting joint alignment and improving biomechanical control during functional movement. As no standardized Mulligan taping protocol specifically targeting an increased elbow valgus angle has been identified in the literature, the taping technique used in this study was standardized by the researchers based on the biomechanical correction principles of the Mulligan Concept. Participants were seated with the elbow in full extension and the forearm in supination. Before tape application, a lateral corrective force was applied to the distal humerus by the researcher and a medial corrective force was applied to the forearm by an independent researcher to reduce the elbow valgus angle. The corrected position was maintained by both researchers while the tape was applied by the researcher.
Placebo TapingBehavioural
Placebo taping was applied using rigid tape without applying any corrective force. The tape was placed over the same anatomical region in all participants in a manner that did not alter elbow joint alignment or produce biomechanical correction. All placebo taping applications were performed by the same physiotherapist.
| Study group | Role | What they receive |
|---|---|---|
| Rigid Taping | Experimental | Participants received rigid taping based on the Mulligan Concept to reduce the elbow valgus angle. Receives: Behavioral: Rigid Taping |
| placebo taping | Placebo comparator | Participants received placebo taping without a corrective force or biomechanical correction. Receives: Behavioral: Placebo Taping |
What is being measured
The primary outcome is the main question the study is designed to answer.
Elbow valgus angle
Elbow valgus angle was assessed before taping and 20 minutes after the taping application. Participants were positioned standing with the shoulder in a neutral position, the elbow in full extension, and the forearm in supination. A digital camera mounted on a fixed tripod was used, and all images were obtained from the same distance, height, and angle. Anatomical reference points defining the longitudinal axes of the humerus and ulna were marked on the skin. Digital images were analyzed using ImageJ software (National Institutes of Health, Bethesda, MD, USA).
Measured: Baseline and 20 minutes after taping
Secondary outcomes (4)
Hand grip strength
Hand grip strength was assessed before taping and 20 minutes after the taping application using a Jamar® Hydraulic Hand Dynamometer (Baseline®, Fabrication Enterprises Inc., White Plains, NY, USA). Measurements were performed in the standardized assessment position recommended by the American Society of Hand Therapists (ASHT). Three measurements were obtained, and the mean of the three measurements was used for analysis.
Measured: Baseline and 20 minutes after taping
Lateral pinch strength
Lateral pinch strength was assessed before taping and 20 minutes after the taping application using a Baseline® Hydraulic Pinch Gauge (Fabrication Enterprises Inc., White Plains, NY, USA). Measurements were performed according to the standardized assessment position recommended by the American Society of Hand Therapists (ASHT). Three measurements were obtained, and the mean of the three measurements was used for analysis. Results were recorded in kilogram-force (kgf).
Measured: Baseline and 20 minutes after taping
Tip pinch strength
Tip pinch strength was assessed before taping and 20 minutes after the taping application using a Baseline® Hydraulic Pinch Gauge (Fabrication Enterprises Inc., White Plains, NY, USA). Measurements were performed according to the standardized assessment position recommended by the American Society of Hand Therapists (ASHT). Three measurements were obtained, and the mean of the three measurements was used for analysis. Results were recorded in kilogram-force (kgf).
Measured: Baseline and 20 minutes after taping
Three-point pinch strength
Three-point pinch strength was assessed before taping and 20 minutes after the taping application using a Baseline® Hydraulic Pinch Gauge (Fabrication Enterprises Inc., White Plains, NY, USA). Measurements were performed according to the standardized assessment position recommended by the American Society of Hand Therapists (ASHT). Three measurements were obtained, and the mean of the three measurements was used for analysis. Results were recorded in kilogram-force (kgf).
Measured: Baseline and 20 minutes after taping
